In the top icon bar, there is a three-button set of icons for running your model.
PP - The PP button starts the preprocessing. You must first PreProcess your model data to create the numerical model from your grid independent data. See Preprocessing your model (V1 p. 69).
WM - The WM button starts the Water Movement simulation. You can only run your water movement simulation after you have preprocessed your data. See Running Your Model (V1 p. 69).
WQ - The WQ button starts the Water Quality simulation. After you have successfully run a water movement simulation to completion, you can run a water quality simulation.
In addition to the three icon buttons, there is a Run menu. In this menu, you can check on and off all three of the above options. Finally, there is an Execute... menu sub-item that runs only the checked items above it. The Execute option can also be launched using the Alt - R - E hot-key sequence.
